Description

Method for preparing organic fertilizer by using EM (effective microorganisms) stock solution

Technical Field

The invention relates to a method for preparing an organic fertilizer by using EM (effective microorganisms) bacterium stock solution, in particular to the technical field of organic fertilizer preparation.

Background

Most of the fruit and vegetable residues are treated as wastes, and a few of the fruit and vegetable residues are prepared into feeds, so that the overall utilization rate is low, and the environment is easily polluted. Animal waste is often used as waste to prepare organic fertilizer, and the traditional composting takes a long time and is decomposed slowly. The straws and the stalks are byproducts of crops such as rice, corn and the like, and are widely applied, such as carbon preparation, environmental protection daily necessities preparation, feed preparation, alcohol production and the like, but straw returning is the most environment-friendly straw application mode, and the stalks grown in the ground nourish soil, enhance soil fertility, improve grain yield and quality, and achieve the virtuous circle of sustainable development. The EM is a microbial life bacterium preparation compounded by 10 microorganisms of 80 microorganisms in five categories of photosynthetic bacteria, lactic acid bacteria, saccharomycetes, gram-positive actinomycetes and filamentous bacteria of a fermentation system. The EM bacteria are easy to live and propagate, form a dominant community of beneficial microbial bacteria, and can stably occupy the ecological status in soil, thereby controlling the propagation of pathogenic microorganisms and the invasion of crops. But also can ensure the stable and high yield of crops and effectively prevent plant diseases and insect pests. Therefore, the EM bacteria are widely applied to the field of fertilizer preparation. The application aims to research a method for preparing an organic fertilizer by adopting EM (effective microorganisms) stock solution.

Compared with the prior art, the invention has the following beneficial effects: the organic fertilizer can improve soil, improve fertility, reduce the use amount of chemical fertilizers and pesticides year by year, and finally does not use chemical fertilizers and pesticides. Finally producing the organic food which is worthy of reality. It has strong affinity with soil and is easy to grow and reproduce in soil, so that it can quickly and stably occupy the ecological position in soil and form advantageous microbial community so as to control the reproduction of pathogenic microorganism and attack on crops. Is the development direction of ecological agriculture, and is more beneficial to the sustainable development of agriculture. After long-term use, the soil is increasingly fertile, earthworms multiply, the water retention, fertilizer storage and air permeability are enhanced, and the formation of a granular structure is promoted. Finally realizing no-tillage planting. Enhance plant metabolism, promote photosynthesis, strengthen leaf protecting film, resist pathogenic bacteria, promote root development, early blooming and fruit bearing, and make the mature period earlier than 7-10 days. Improve the product quality, improve the taste and increase the yield of crops.
